Interconnections of implantable lead conductors and electrodes and reinforcement therefor
First Claim
1. An implantable lead comprising:
- a lead body extending from a lead proximal end portion to a lead distal end portion and having a lead intermediate portion therebetween, the lead body including one or more longitudinally extending lumens;
a conductor received in, and extending along, a first lumen;
an electrically conductive interposer coupled with the conductor, the interposer received, at least in part, in the first lumen;
a tubular electrode co-axial with, and overlying portions of, the lead body; and
wherein a portion of a first lumen wall compressively urges the interposer, at least in part, toward an inner surface of the tubular electrode.

Abstract
An implantable lead comprises a lead body extending from a lead proximal end portion to a lead distal end portion. The lead body includes one or more longitudinally extending lumens. A conductor is received in, and extends along, a lumen. In varying examples, the implantable lead further comprises a tubular electrode co-axial with, and overlying portions of, the lead body. In one example, a lumen wall is sized and shaped to urge an electrically conductive interposer coupled with the conductor toward an inner surface of the electrode. In another example, a ring member is disposed within a lumen and the conductor is drawn and coupled thereto. In yet another example, an electrically conductive connector couples a first and a second conductor via grooves or threads. In a further example, an axial support member couples a distal end electrode and the lead body. Methods associated with the foregoing are also discussed.
